1. Isolation. Use polyester staple fiber needle-punched geotextile to isolate building materials with different physical properties (such as soil and gravel, soil and concrete, etc.).
2. Filter. Effectively intercept soil particles, fine sand, small stones, etc. to maintain the stability of water and soil engineering
3. Drain. Drainage channels can be formed inside the soil to drain excess liquid and gas from the soil structure.
4. Reinforcement. Enhance the tensile strength and deformation resistance of the soil, enhance stability, and improve the quality of the soil.
5. Protection. Prevent the soil from being damaged by external forces and protect the soil.
6. Anti-puncture. Combined with the geomembrane, it becomes a composite waterproof and impermeable material, which plays a role of preventing puncture.
